If you are looking to buy a Graphics card, you should check the collection of AMD high end graphics card. AMD cut down the prices of its high end graphics card to become more competitive with NVIDIA‘s latest offering. With the NVIDIA GTX 660 Ti finally outed by the company.

The prices have dropped accordingly

1GB 7850 down $40 to $190

2GB 7850 down $40 to $210

2GB 7870 down $50 to $250

3GB 7950 down $30 to $320

The price drops range from 10-20 percent, which are respectable Discounts. These cheaper prices are the result of healthy competition, and while this might be a bit off topic, it needs to be said: this is why AMD needs to hang in the market against both NVIDIA and Intel. Better products (Kepler) and cheaper prices are sure to come because of it.

As these days, Computers are a need of everybody, the Graphics are a very important part of the computer for game play and other things. Nowadays the games are made on a vast scale and the games look so real that you hardly differentiate between a game and the real world. To make games look like this, new Graphics Processing Unit (GPU) is included in the Computer only for Graphics. Their are two main Companies which makes the GPU’s for computers – AMD Radeon and NIVIDIA . We have tried to differentiate between them to see which one is better than other.

Early days of graphics on the PC saw 3D cards like Nvidia’s RIVA 128 and TNT2 take on ATI’s Rage and Rage 128. But it was Nvidia who presaged the modern GPU or Graphics Processing Unit with the mighty GeForce 256 in 1999. ATI responded in 2000 with the Radeon graphics card. Ever since, successive generations of GeForce and Radeon GPUs have been leapfrogging each other in the race for graphics supremacy. Nvidia has the early advantage over the ATI’s Radeon. But in 2002 ATI turned the tables with the awesome Radeon 9700 Pro. The first GPU with fully programmable shaders, the 9700 Pro was massively more powerful than any graphics chip before.

Now Move into mid-range territory and direct comparison between ATI and Nvidia is currently a bit tricky. That’s because Nvidia is yet to release more affordable chips based on Fermi, the new DX11 architecture that underpins the GTX 480 and 470 GPUs. Consequently, the Radeon HD 5770 (£125), Radeon HD 5670 (£85) and Radeon HD 5570 (£72) are lording it without any DX11 competition and Nvidia makes older chipsets based on DX10 tech, such as the GeForce GTS 250 (£125) and GeForce GT 240 (£72).

Conclusion: What becomes of AMD graphics after two fruitless attempts at winning over the top-end market? The AMD Radeon HD 6870 failed to reach top-level performance that many expected, and was relegated to fighting off an army of factory-overclocked GeForce GTX 460′s that sell at a better price point. Now the Radeon HD 6970 proves that AMD doesn’t have a single-GPU answer to NVIDIA’s GeForce GTX 580. The DX11 discrete graphics market is already saturated with AMD Radeon HD 5000 series, diced into portions so thin that a mere $10 separates some products, leaving little room for additional growth. With the convincing likelihood that AMD’s Radeon HD 6900-series will miss the fast-approaching holiday season and the sales opportunities it brings.

Rarely, people know about GPU and CPU is known by all of us and is better known as brain of computer. But what is GPU? and Difference Between them?

At older times CPU – Central Processing Unit handles all the processes and derive them to users. Than advancement came in the era of Processors and they started crunching more information at faster rate. But researchers need more speed out of the processor. So they elevated Graphical Processing from CPU to GPU – Graphics Processing Unit and this change not only increased processing speed but due integrated processing unit for Graphics betterised Graphics on our screens.

The new GPU can perform common graphics routines really fast. GPUs were originally developed to render 2D graphics but according to need it became faster and more specialized in its task. Insight64 principal analyst Nathan Brook wood described the unique capabilities of the GPU this way:

[quote]GPUs are optimized for taking huge batches of data and performing the same operation over and over very quickly, unlike PC Microprocessors, which tend to skip all over the place.[/quote]

Coming onto architecture GPU’s consist hundreds of cores which can handle various threads at a time in respect to CPU which have only few cores with lots of cache memory that can handle a few software threads only. GPU is also efficient in cost and power aspects. GPU’s make software to run at 100x faster speed than CPU.

With more advancement now GPU’s can be used for any purpose, not just graphics or video related purposes. Nvidia CUDA, the first true GPGPU which basically, is a way to use the GPU(s) on a video card as general-use supplemental processors. GPU-accelerated computing has now grown into a mainstream movement supported by the latest Operating systems from Apple (with Open CL) and Microsoft (using Direct Compute). The combination of a CPU with a GPU can deliver the best value of system performance, price, and power.

Nvidia launches the new Geforce GTX 670 Graphics card with fabulous performance and exceptional power efficiency. GTX 670 is based on the Nvidia’s next generation Kepler Architecture which dramatically improves the performance, power efficiency and quit operations for PC gamers. New anti-aliasing mode eliminates the jaggies without sacrificing the frame rate. Nvidia sround lets you game on three monitors with single card.

Features of Nvidia Geforce GTX 670

NVIDIA Surround with Up To Four Monitors – By this we can play games on three different monitors while using the single graphics card at 5760 x 1080.

NVIDIA GPU Boost – It boost the clock speed while playing 3D games by this GPU gives its best performance.

New Anti-aliasing Mode – Anti-aliasing smooths down the jagged edges and eliminates the jaggies without sacrificing the frame rate. In GTX 670 their are two anti aliasing modes first is FXAA that produces beautiful smooth lines with minimal performance impact. Second is TXAA it is an in-game option that combines MSAA and temporal filtering and post processing for every higher visual fidelity.
